Kallmünz Stone Bridge
Highlight • Bridge
A pair of scissors and a cross tell the story of an atonement and a deadly dispute. Here a tailor should have stabbed a baker or vice versa. In a modification of the above legend, a tailor and a baker, both from Kallmünz, are said to have fought a duel on the Naabbrücke, which ended fatally for both.

House without a Roof (Kallmünz)
Highlight • Cave
The house consists of a natural cave in the dolomite rock, the opening of which is closed off by a plastered wall with a door and windows. Inside, there is a hallway, a living room, two storage rooms fitted into rock niches, and a historic smokehouse.
The oldest known mention of the cave dwelling is found in a document dated 1707, preserved in the land registry archive in Amberg. In the 19th century, it was also referred to as the "House Under the Rock." In 1908, it was sold to the owner of the blacksmith's shop located across the road, and it remains in his family's possession. The last permanent resident left the house in 1937 because he developed rheumatism due to the damp cave air.
